Product Introduction

The second-class standard mercury thermometer measures the temperature using the principle of thermal expansion and contraction of mercury in the temperature-sensing bubble and capillary. Its structure is divided into two types: internal standard and rod type. It is mainly used as a standard for measuring working thermometers. It can also be used for precision temperature measurement. The measurement range is (-30°C～+300°C), and the division value is 0.1°C. With a zero mark.
